Fault Stability Assessment in Tectonically Active Geothermal Fields Through Integrated Stress Analysis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The Tulu Moye geothermal field in the actively deforming Main Ethiopian Rift presents substantial potential for renewable energy production, where interactions between fault systems, hydrothermal fluids, and tectonic activity require careful management for sustainable development. Here we present a first‐order assessment of fault stability and

Linked and fully coupled 3D earthquake dynamic rupture and tsunami modeling for the Húsavík–Flatey Fault Zone in North Iceland [PDF]

Solid Earth
Tsunamigenic earthquakes pose considerable risks, both economically and socially, yet earthquake and tsunami hazard assessments are typically conducted separately.

The 2001 M_w 7.6 Bhuj earthquake, low fault friction, and the crustal support of plate driving forces in India [PDF]

, 2011
We present a source model for the 2001 M_w 7.6 Bhuj earthquake of northwest India. The slip distribution suggests a high stress drop (~35 MPa) and, together with the depth distribution of aftershocks, that the entire crust is seismogenic. We suggest that

Interseismic coupling and seismic potential along the Central Andes subduction zone [PDF]

, 2011
We use about two decades of geodetic measurements to characterize interseismic strain build up along the Central Andes subduction zone from Lima, Peru, to Antofagasta, Chile.

Influence of the Loading Stiffness on Sheared Granular Fault Gouge, and Applicability to Slip‐Weakening Theory

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Tectonic faults can slip in a spectrum of fault slip behaviors, from aseismic slip and slow ruptures to elasto‐dynamic earthquakes. Following frictional theory, laboratory experiments have shown that the basic ingredient that may control this transition is the interaction between the fault stiffness and the surrounding elastic medium.

Tectonic Control of Aseismic Creep and Potential for Induced Seismicity Along the West Valley Fault in Southeastern Metro Manila, Philippines

GeoHazards
Vertical creep along 15 ground ruptures within a 15 km long and 1.5 km wide zone has been occurring along the southeastern part of Metro Manila. Though the unusually high rates of vertical slip point to excessive groundwater withdrawal as the trigger ...

Poroelastic Bulk Controls on Shear Localization in Fault Gouge During Earthquake Rupture: Insights From a Hybrid Numerical Framework

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Seismic ruptures that extend over kilometers along faults originate in shear zones only millimeters thick. We present a hybrid numerical framework coupling the spectral boundary integral method (SBIM) for the poroelastic bulk with a staggered‐grid finite difference method (FDM) for the fault gouge.
